T 0 all whom it may concern: illustrated in :the drawings and hereinafter'5 Be it known that I, \ViLLi'AM C. S'rnvnNs, more fully described.

a citizen of the United States, and a resi On the drawings 1 dent of the city'of Akron, in the county of Figure 1, is a front elevation of a shuttle 5 Summit'and State of Ohio, have invented. equipped with a folder device embodying certain new and useful Improvements in the principles of my invention. a Wrapping-Machine F olders;and.ldo hereby Fig. 2 is a bottom plan view thereof; declare that'the following is a full, clear, Fig. 3 is a detail section, taken on line and exact descriptionof the same,--refer- 3-43 of Fig. -1.,

Then it is des red. to re form thepmfpose for 'whichit is designed. lease the lunged section. the tail-of the lever I The invention (in a"p refe'rred form) is pressed downwardly toward thex-taillO of the detent lever, thus releasing the locking end of said detent lever, whereupon the same may be swung laterally carrylng the,

finger 9 thereon out of the notch 6' and permitting the shuttle to be opened. Mounted on the face of the shuttle diametrically opposite the hinged section thereof is a stud shaft ll upon which a paper reel is mounted, carrying a reel of wrapping ma terial 16.

An angled bracket plate 17 is pivotally and obliquely secured upon the face of the shuttle by means of a bolt 18, and secured on said plate is a folding device 19 consisting of a sheet of metal bent to afford a tapering nozzle 20 comprising an inner and relatively narrow plate or member, an outer wider plate or member, and a lip. 21 integral with the outer fold and turned over the inner plate or member.- The opposite end of said nozzle wider and flaring to receive the paper or other material therein. Said folding device is secured on said braeket plate 17 in any suitable manner with the tapered end of the nozzle directed outwardly. Mounted adjacent said tapered end of the folding device and set in the face of the shuttle is a stud shaft 22 which is inclined sligl'itly as shown in Fig. 3. The lower end 23 of said stud shaft engages perpendicularly tl'u'o'ugh the wall or face of the shuttle, and a nut 2a is provided thereon which may be loosened to permit an adjustment of the upper angled portion 22 into any desired position. Journaled on said stud shaft 22 is a creasing roller 25 or if preferred, the stud shaft may be merely rounded or provided with a convex surface over which the paper or other wrapping material may be drawn to the article to be wrapped. A washer 26 the opposite surfaces of which are inclined conforming to the angularity of the portions 22 and 23 of the stud shaft is engaged upon said stud shaft between said rollern 25 and the face of the shuttle.

The operation is as follows:

The paper or other wrapping material is drawn from the reel through the folding nozzle 19 around the guide roll 25 and thence to the article, and when the shuttle is rotated, of coul'TIe, the wrapping material is applied to the article. The pivotal mount i'ng ofthe folding nozzle 19 by means of the bolt 18 on the face of the shuttle, permits the nozzle to properly aline itself be tween the roller 25 and the periphery ofthe constantly decreasing reel of paper 16. As clearly shown' in Fig. 4, at the entrance end of the folder nozzle, the inner 'fold plate over which the lip 21 extends is rounded at its end beneath the flaringend of the upper fold of the plate, so that an easy entrance forthe wrapping material is provided. The

roller 25 may be adjusted into various,positions by loosening the nut 24; so that the proper operating position of the roller 25 with respect tothe article being wrapped may be easily secured.

It may be found desirable at times after adjusting the nozzle 19 properly to feed the wrapping material, to clamp the same in adjusted position, which readily may be accomplished by tightening the bolt 18, as shown in the drawings. 1

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention 1. In a device of the class described, paper-supporting means, folding mechanism to fold the paper led from said meansv and a creasing member to crease the fold in the paper, saidfolder mechanism so constructed as to automatically aline itself into proper position between said means and member as the direction of feed of said paper changes with a decrease in the supply thereof.

2. In adevice of the class described, the combination with paper-supporting mechanism ,of, a folding device for said paper mounted to automatically adjust itself to said mechanism as the direction of feed of the paper to said device varies. 3. In a device, of the class described, means for supporting a roll of paper thereon, a roller adapted to have the paper drawn.

thereover, anda folding device adapted to automatically aline itself to compensate for the varying diameter of the roll of paper as it IS unwound.

4. In a device of the class described; an

angularly inclined means for carrying a roll of paper, a creasing roller having an angular inclination complementaltherewith, and an automatically alining folding device through which the paper passes from the roll to the creasing roller.

5. In a wrapping machine of the class described," an angularly inclined creasing roller, an angular-1y. inclined shaft for carrying a roll of paper, and a pivotall mounted folder between said roller and sha. t adapted to automatically position itself to compensate for the varying diameter of the roll of paper during the wrapping operation. 6. In a device of the class described, the combination with paper-supporting mechas nism of a foldin device for said paper mounted to automatically adjust itself to said mechanism as the direction, of feed of the paper to said device varies, said device.
